另一方面，爲了維持改善地球環境，儘可能減輕環境 負荷之電池之硏究開發也十分活絡。其中，將通常無意識 下所浪費之能量轉變成電氣能量並進行充電而將該電氣能 量當做攜帶機器等之電源來利用之構想被廣泛注視。 專利文獻1設載著，使長度方向磁化之複數個永久磁 鐵以微小距離且同極彼此相對之方式一體化之可動磁鐵， -5- 200845536 於相鄰之複數線圈之極性爲逆極性串聯之線圈中移動之方 式之振動發電機。 專利文獻2記載著，使複數個磁鐵之相同極性之面相 對接合，使相鄰之線圈之極性爲逆向連結之構成之發電機 〇 [專利文獻1]日本特開2006-296 1 44號公報 [專利文獻2]日本特表2006-523081號公報 【發明內容】 然而，本發明之發明者進一步針對以提高發電效率爲 目的之條件進行檢討。結果，發現使由磁鐵之長度（磁鐵 長度）及微小距離（隔離件厚度）之合計尺寸所決定之磁 鐵間距、及由線圏長度及線圈間隔之合計尺寸所決定之線 圈間距成爲一致，係利用複數個磁鐵及複數個線圈構成振 動型電磁發電機時之最重要的要件。 φ 未能滿足該條件時，發生於複數個線圈之電壓之相位 會偏離，而使各電壓互相抵銷，而有合成輸出電壓降低之 問題。然而，專利文獻1並沒有磁鐵間距及線圈間距必須 一致之記載，亦未明示如何決定基準之磁鐵長度。 此外，專利文獻2所示之發電機之構成要素之複數個 磁鐵’未使用磁鐵隔離件而直接將同極相對接合。此外， 複數個線圈之倂聯亦未配設線圈間隔。此外，未明示以提 高發電效率爲目的之磁鐵尺寸及線圈尺寸之具體決定方法 -6 - 200845536 此外，如專利文獻2所示之直接接合磁鐵之同極時， 因爲會發生滅磁，而使發電效率劣化。此外，因爲同極之 反作用力極大，而有接合作業困難之問題。 本發明之目的係在提供，藉由針對傳統之振動型電磁 發電機，明確訂定不明確之以提高發電效率爲目的之具體 條件，提供更小型之高發電效率之振動型電磁發電機。 本發明之振動型電磁發電機，係由：串聯著複數之螺 線管線圈之發電線圈；及含有以可於發電線圈之內側在捲 軸方向移動，相對之磁極爲互相同極之方式配置之複數之 磁鐵之可動磁鐵；所構成。其次，複數之螺線管線圏，具 有所定之線圈間隔且以互相相反方向進行捲繞，可動磁鐵 ，介由所定厚度之磁鐵隔離件以同極相對之方式進行接合 ，此外，複數之各螺線管線圈之線圈長度及線圈間隔之合 計尺寸之線圈間距，與各可動磁鐵之磁鐵長度及磁鐵隔離 件之厚度之合計尺寸之磁鐵間距爲大致相等，且線圈長度 短於磁鐵長度。 此外，本發明係具備：串聯著複數之螺線管線圈之發 電線圈；及含有以可於發電線圈之內側在捲軸方向移動， 相對之磁極爲互相同極之方式配置之複數之磁鐵之可動磁 鐵；且，複數之螺線管線圈，具有所定之線圈間隔且以互 相相反方向進行捲繞，可動磁鐵，介由所定厚度之磁鐵隔 離件以同極相對之方式進行接合，此外，複數之各螺線管 線圈之線圈長度及線圈間隔之合計尺寸之線圈間距，與各 可動磁鐵之磁鐵長度及磁鐵隔離件之厚度之合計尺寸之磁 -7- 200845536 鐵間距爲大致相等，且線圈長度短於磁鐵長度而構成之振 動型電磁發電機之製造方法。 該振動型電磁發電機之製造方法之特徵爲含有：製作 具有所定之線圈徑及所定之每單位長度之捲數，線圈長度 爲線圈徑之至少3倍以上之螺線管線圈之步驟；測定使具 有所定之磁鐵徑，與線圈長度爲大致相同長度之磁鐵以一 定之通過速度通過螺線管線圏中時之輸出電壓之啓動特性 φ 之步驟；求取啓動特性之從最大振幅之10%到達90%爲止 之啓動時間之步驟；以及以利用啓動時間及通過速度所求 取之距離之大致2倍之長度做爲磁鐵間距之長度之步驟。 依據本發明，因爲可以設計最佳之磁鐵隔離件、磁鐵 、線圈、以及線圈間隔，故可得到可提高發電效率之振動 型電磁發電機。 依據本發明，爲增加磁鐵數及線圈數時之最佳設計， 可得到最大發電電力之效果。此外，因爲可以設計最佳之 φ 磁鐵隔離件、磁鐵、線圈、以及線圈間隔，故可得到可縮 小發電機尺寸之效果。 【實施方式】 以下，參照第1圖〜第12圖，針對本發明之一實施 形態進行說明。本實施形態時，係針對應用於除了來自外 部之振動以外，藉由使設置於螺線管線圈中之磁鐵移動來 進行發電之振動型電磁發電機之例進行說明。 首先，針對本發明之振動型電磁發電機之具體構成例 -8 - 200845536 進行說明前，參照第1圖〜第3圖，針對由可動磁鐵及螺 線管線圈所構成之發電機進行說明。 第1圖係由1個圚筒型磁鐵2及1個螺線管線圈1所 構成之振動型電磁發電機10之構成例及輸出電壓波形之 例圖。 構成振動型電磁發電機1 0之螺線管線圈1之長度， 大致等於圓筒型磁鐵2之長度。其次，1個圓筒型磁鐵2 φ 沿著螺線管線圈1之捲軸方向通過時所得到之輸出電壓以 輸出電壓波形3來表示。 輸出電壓波形3之周期大約爲磁鐵長度或線圏長度（ 螺線管線圈之長度）之2倍，而爲大致等於正弦波之波形 之1周期份之波形。亦即，第1圖中，以輸出電壓波形之 橫軸做爲時間軸時，1周期之時間，係以磁鐵長度之2倍 之長度距離除以通過速度所得到之値。 然而，本發明之振動型電磁發電機，係由螺線管線圈 φ 、及在螺線管線圈中動作之可動磁鐵所構成。可動磁鐵係 以使相同極性相對接合之複數個磁鐵所構成。此外，螺線 管線圈係由串聯逆極性之複數個線圈所構成。其次，本發 明之振動型電磁發電機之輸出電壓，係藉由在.螺線管線圈 中動作之可動磁鐵使各螺線管線圈所產生之輸出電壓而得 到。此時，各螺線管線圈所產生之輸出電壓之波形，係以 第1圖所示之電壓波形爲基本。其次，配合全部線圈所發 生之電壓之相位，使該電壓成爲最大輸出極爲重要。因此 ’加上磁鐵長度及磁鐵隔離件之厚度之磁鐵間距、及加上 -9- 200845536 線圈長度及線圈間隔之線圈間距必須大致相等。 此外，磁鐵之材質相同時，爲了得到小型且具有更高 發電效率之發電機，如何以較短之磁鐵長度獲得較大之輸 出電壓係重要課題。因此，本發明之發明者，在各種條件 下，實施本發明之振動型電磁發電機之特性的檢証。 第2圖係由1個可動磁鐵25、及3個螺線管線圈（第 1螺線管線圈2 1〜第3螺線管線圈23 )所構成之振動型電 磁發電機20之剖面圖。 相鄰之螺線管線圏，具有所定之間隔24。線圈之捲繞 方向，係各相鄰螺線管線圈互相逆向之正·逆·正方向。 將該串聯之第1螺線管線圈21〜第3螺線管線圈23，稱 爲發電線圈26。可動磁鐵25之長度，等於線圈長度及線 圈間隔之合計長度（例如，螺線管線圈21及間隔24之合 計長度）。 第3圖係可動磁鐵25通過以正·逆·正之極性串聯 之第1螺線管線圈21〜第3螺線管線圈23時之輸出電壓 波形之槪念圖。第3圖之橫軸刻度係對應於磁鐵長度（= 線圈長度）之時間。 第3圖中，表中之數字係各螺線管線圈之輸出電壓及 合成輸出電壓之振幅比。 第1螺線管線圈21〜第3螺線管線圈23之極性分別 爲正·逆·正。因此，發生於各第1螺線管線圈21〜第3 螺線管線圈23之電壓，以會對應線圈長度之時間產生相 位偏離，同時，改變極性。 -10- 200845536 此外，第1螺線管線圈21〜第3螺線管線圈23係相 互串聯。因此，所取得之電壓，係加上第1螺線管線圈2 1 〜第3螺線管線圈23所發生之電壓之合成輸出電壓。此 時，得到第3圖所示之合成輸出電壓波形。 其次，參照第4圖之剖面圖，針對本發明之振動型電 磁發電機40之構成例進行說明。 振動型電磁發電機40係由1個可動磁鐵48、及3個 φ 螺線管線圈（第1螺線管線圈41〜第3螺線管線圈43 ) 所構成。 相鄰之螺線管線圈，隔著所定之間隔44。線圈之捲繞 方向，係相鄰螺線管線圈互相爲逆向之正·逆·正方向。 將該串聯之第1螺線管線圈41〜第3螺線管線圈43，稱 爲發電線圈4 9。 可動磁鐵4 8係使長度方向磁化之相同長度之2個磁 鐵45、46介由所定厚度之非磁性體所構成之磁鐵隔離件 φ 47以同極進行一體之相對接合。 磁鐵長度及磁鐵隔離件47之合計尺寸之磁鐵間距5 1 ，等於螺線管線圈及螺線管線圈間隔之合計尺寸之線圈間 距52。只是，即使在該條件下，以線圈長度短於磁鐵長度 爲佳。 第5圖係2個磁鐵45、46通過第4圖所示之正·逆 •正連結之第1螺線管線圈41〜第3螺線管線圈43時之 輸出電壓波形之槪念圖。第5圖中，表中之數字係各螺線 管線圈之輸出電壓及合成輸出電壓之振幅比。 -11 - 200845536 極性不同之2個磁鐵45、46通過各螺線管線圈時， 於各螺線管線圈，發生相位於對應線圈長度之時間產生偏 離之電壓。由該等電壓之全部所合成之輸出電壓，即爲第 5圖所示之合成輸出電壓波形。 振動型電磁發電機20、40如第2圖及第4圖所示， 磁鐵及螺線管線圈係以接近之方式配置。因此，如第3圖 及第5圖所示，具有輸出電壓被合成，使其振幅之一部份 φ 成爲數倍之基本特性。本發明之發明者希望利用該基本特 性來增大振動型電磁發電機之輸出電力。其次，本發明之 振動型電磁發電機時，磁鐵間距5 1及線圈間距52相等係 極爲重要的一點。 此處，參照第6圖，針對圓筒型磁鐵60於空間所形 成之磁場之分佈進行說明。第6圖係圓筒型磁鐵60於空 間所形成之磁場分佈之剖面圖例。 由第6圖可知，磁鐵之端面附近之磁場，可以到達比 φ 圓筒型磁鐵60之長度更長之方向。此外，圓筒型磁鐵60 之端面附近之磁場之方向，相對於圓筒型磁鐵60之長度 方向爲平行。因此，必須藉由使線圏長度短於磁鐵長度來 有效地結合螺線管線圈及平行於磁鐵之長度方向之磁場。 到目前爲止之說明中表示，爲了提高發電效率，必須 使磁鐵間距及線圈間距相等，且必須使線圈長度短於磁鐵 長度。以下，針對以提高發電效率爲目的之最佳磁鐵長度 及磁鐵間距之決定方法進行說明。 第7圖係使磁鐵長度不同之4種類之圓筒型磁鐵以速 -12- 200845536 度1 · 2 m / s通過一定線圈長度之螺線管線圈中所得到之輸 出電壓特性之實測値例。 4種類之圓筒型磁鐵係直徑同樣爲4mm，然而，磁鐵 間距爲不同之8mm、16mm、24mm、32mm之構成。 螺線管線圈係內徑6mm、各單位長度之捲繞數60次 、線圈長度30mm之構成。 由第7圖可知，磁鐵長度增加時之輸出電壓之啓動特 0 性與任一磁鐵長度時大致相同。其次，輸出電壓之最大値 ，於磁鐵長度從8mm增加至16mm、磁鐵長度從16mm增 加至3 2mm時，亦大致一定。但是，隨著磁鐵長度之增長 ，輸出電壓之最大値的持續時間也變長。 此外’如第7圖所示，啓動特性幾乎不會因爲磁鐵長 度而改變。因此，決定啓動特性之要因，係磁鐵之直徑及 螺線管線圈之尺寸，尤其是，應爲螺線管線圈之內徑。因 此，藉由使螺線管線圈之內徑接近磁鐵之直徑，可以使啓 φ 動時間更爲縮短。 此處，將重點置於發生最大輸出電壓之長度16mm、 24mm、3 2mm之圓筒型磁鐵，依據第7圖之輸出電壓之啓 動特性，求取輸出電壓從最大値之10%到達90%之時間。 此時，如圖中所示，約爲5ms。此時，因爲磁鐵之移動速 度爲1.2m/s ’對應啓動時間5ms之2倍之移動距離爲12 (m/s) x5 (ms) x2 = 12mm。 亦即’磁鐵長度爲12mm，使輸出電壓大致等於最大 値’同時，可以使磁鐵長度爲最短。 -13- 200845536 第8圖係使一定磁鐵長度之圓筒型磁鐵通過線圈長度 不同之3種類之螺線管線圈中時之輸出電壓特性之實測値 例。 圓筒型磁鐵係直徑4mm、磁鐵長度8mm之構成。 螺線管線圈係各單位長度之捲數相等，線圈長度爲不 同之7mm、10mm、30mm之構成。 由第8圖可知，磁鐵長度爲8mm時，線圈長度即使 從7mm增長爲10mm，輸出電壓亦只增加少許。此外，線 圈長度即使從7mm增長至30mm，輸出電壓之最大振幅也 幾乎爲一定之値（約0.5V)。 亦即，相對於長度爲8mm之一個磁鐵，如第1圖所 示，使線圈長度成爲與磁鐵長度相同之長度之8mm，輸出 電壓大致爲最大値（飽和電壓）。 參照第7圖及第8圖，針對可動磁鐵爲一個之振動型 發電機例進行說明。然而，由複數個磁鐵（至少爲2個以 上）所構成之可動磁鐵、及複數個螺線管線圈所構成之振 動型發電機40時，在相同條件下，亦可針對所定線圈尺 寸選擇輸出電壓爲最大之最短磁鐵間距。 亦即，使磁鐵長度及隔離件厚度之合計尺寸之磁鐵間 距、及線圈長度及線圈間隔之合計尺寸之線圈間距相等， 可以得到高發電效率，且可縮小全體之尺寸。此外，以使 磁鐵間距及線圈間距成爲相等且使線圈長度短於磁鐵長度 爲佳。 如此，由複數個磁鐵及複數個螺線管線圈所構成之振 -14- 200845536 動型電磁發電機40時，可針對所定之螺線管線圈尺寸選 擇輸出電壓爲最大之最短之磁鐵長度。因此，即使尺寸較 小’亦可得到高發電效率之振動型電磁發電機40。 以下，針對求取以提高發電效率爲目的之最佳磁鐵間 距之步驟，進行說明。 (1 )首先，製作具有所定之線圈徑及所定之單位長 度之捲數，線圈長度至少爲線圈徑之3倍以上之螺線管線 圈。 (2)其次，使具有所定磁鐵徑、線圈長度大致爲相 同之長度之磁鐵以一定速度通過該螺線管線圈中，測定此 時之輸出電壓之啓動特性。 (3 )求取該啓動特性時之從最大振幅之1 0%到達 90%之時間。 (4 )結果，利用所求取之時間及通過速度，求取距 離之大致2倍之長度，做爲求取之磁鐵間距。 求取磁鐵間距後，將螺線管線圈之線圈長度及線圈間 隔之合計尺寸設定成與磁鐵間距相等，且使磁鐵長度長於 上述之螺線管線圈之線圈長度之條件下，設定線圈間隔及 磁鐵隔離件之尺寸條件。如此，可以得到接近最大輸出之 電壓，且可縮小發電機本體之尺寸之振動型電磁發電機。 此外，如上面所述時，所定之線圈徑、所定之各單位 長度之捲數、以及所定之磁鐵徑，係代表使用於所製作之 振動型電磁發電機之尺寸。 此處，參照第9圖之立體圖，針對振動型電磁發電機 -15- 200845536 40之外觀構成例進行說明。 第9圖A係分解用以構成振動型電磁發電機40之各 構件之狀態之立體圖。 第9圖B係組合各構件之振動型電磁發電機40當中 之收容盒55之部份透視圖。 第1螺線管線圈41〜第3螺線管線圈43，隔著螺線 管線圈間隔44，捲繞於收容著可動磁鐵48之圓筒型之收 容盒5 5之外周面。第1螺線管線圈4 1〜第3螺線管線圈 43係串聯。其次，各螺線管線圈以互相反方向進行捲繞， 分別爲正捲、逆捲、及正捲。 從第1螺線管線圈41及第3螺線管線圈43分別延伸 出線圈端部5 3，連結於未圖示之外部構件（負荷）。 爲了將可動磁鐵48收容於收容盒55內，於收容盒55 之兩端，裝設著端蓋56。端蓋56係由可緩和對可動磁鐵 之衝擊之樹脂等所形成。 爲了使可動磁鐵48可於收容盒55之內部順暢動作， 而使其於第1螺線管線圈41〜第3螺線管線圈43之內側 可於捲軸方向進行移動。因此，第1螺線管線圈4 1〜第3 螺線管線圈43可產生電壓而具有發電機之機能。 此處，參照第1 〇圖，針對實際利用振動型電磁發電 機40所得到之輸出電壓波形之實測値例進行說明。 可動磁鐵係將2個直徑4mm、長度8mm之Nd (鈸） 磁鐵介由厚度1.5mm之磁鐵隔離件實施同極相對接合之構 成。 -16- 200845536 螺線管線圏係將3個線圈長度6.5mm、線圈內徑5mm 、捲數3000次之線圏以線圈間隔3mm實施正·逆·正之 串聯而構成。 其次，第10圖係使可動磁鐵以速度約1.2m/s沿著螺 線管線圈中之捲繞線軸方向移動時之輸出電壓波形。 將第10圖與第5圖之合成輸出電壓波形進行比較， 兩者相當一致。其正代表參照第1圖至第5圖進行說明之 φ 內容之適當性。 此處，參照第1 1圖及第12圖，針對磁鐵隔離件之材 質不同之各可動磁鐵之磁束密度例進行說明。 第1 1圖係圚筒型磁鐵、及介由磁鐵隔離件接合圓筒 、 型磁鐵之可動磁鐵之構成例。 第1 1圖A，係圓筒型磁鐵61之構成例。圓筒型磁鐵 6 1之軸方向之長度約爲1 〇mm，直徑約爲5 mm。 第1 1圖B係磁鐵隔離件7 1、81之構成例。形成磁鐵 φ 隔離件71之材料，係利用例如樹脂做爲非磁性體材料。 形成磁鐵隔離件81之材料係利用例如純鐵做爲磁性體材 料。磁鐵隔離件71、81之軸方向之長度約爲2mm，直徑 約爲5mm。 第11圖C係可動磁鐵70、8 0之構成例。可動磁鐵 70係介由非磁性體材料所形成之磁鐵隔離件7 1使3個圓 筒型磁鐵6 1以同極相對狀態進行接合。另一方面，可動 磁鐵80係介由磁性體材料所形成之磁鐵隔離件8 1將3個 圓筒型磁鐵6 1以同極相對之狀態進行接合。 -17- 200845536 第12圖係圓筒磁鐵61及可動磁鐵70、80所產生於 前述圓筒磁鐵61及可動磁鐵70、80之長度方向之表面附 近之磁束密度之測定結果例。 第1 2圖A係1個圓筒型磁鐵6 1之磁束密度之測定結 果。 第1 2圖B係可動磁鐵70之磁束密度之測定結果。 第1 2圖C係可動磁鐵80之磁束密度之測定結果。 第12圖A〜第12圖C中，於代表磁束密度之縱軸， 附有等間隔之刻度（B :〜B6 )，用以供各圖進行比較。 如第12圖A所示，一般而言，圓筒型磁鐵61之端部 (N極及S極附近），因爲磁束集中而有較高之磁束密度 〇 此外，如第12圖B及第12圖C所示，同極相對接合 之可動磁鐵之N極及S極附近，具有高於1個圓筒型磁鐵 6 1之磁束密度之峰値。此係因爲同極相對接合，磁束相斥 而提高磁束密度。 此外，與第12圖B及第12圖C時相比，可知含有磁 性體材料所形成之磁鐵隔離件81之可動磁鐵8 0之磁束密 度之峰値，高於含有非磁性體材料所形成之磁鐵隔離件7 1 之可動磁鐵70。此時，可動磁鐵8 0之峰値，比可動磁鐵 70之峰値高出3/2倍程度。其係高透磁率之磁性體材料所 形成之磁鐵隔離件8 1，容易牽引來自圓筒型磁鐵6 1之磁 力線，不但具有較高之磁束指向性，且磁束密度也更高。 依據第12圖A〜第12圖C之測定結果，利用含有磁 -18- 200845536 性體材料所形成之磁鐵隔離件81之可動磁鐵8 0構成振動 型發電機時，磁束密度較高，與螺線管線圈交叉之磁束較 多。因此，磁鐵隔離件所使用之材質爲磁性體材料時，與 非磁性體材料時相比，振動型電磁發電機之發電效率更高 〇 如以上之說明所示，藉由明確訂定以提高振動型電磁 發電機40之發電效率爲目的之具體條件，可以適當設計 0 振動型電磁發電機4 0之磁鐵間距及線圈間距適。因此， 具有可得到小型且高發電效率之振動型電磁發電機4 0之 效果。 此外，振動型電磁發電機40之構成簡單。因此，組 裝時之製程較爲容易，具有可得到不易損壞、高信賴性之 振動型電磁發電機40之效果。 此外，磁鐵隔離件爲磁性體時，因爲可提高磁束密度 ，具有可提高振動型電磁發電機之發電力之效果。因此， φ 重視發電量時，即使外尺寸小於利用非磁性體材料所形成 之磁鐵隔離件之振動型電磁發電機，亦可得到相同發電量 。此時，亦可減少螺線管線圈之捲繞數。因此，具有振動 型電磁發電機可更爲小型化且輕量化之效果。此外，藉由 減少使用構件之量，具有降低成本之效果。 另一方面’藉由磁鐵隔離件爲非磁性體，與磁鐵隔離 件爲磁性體時相比，具有製造較爲便宜之效果。此外，因 爲非磁性體可以使用塑膠等之合成樹脂，具有加工性優良 、高製造速度之效果。 -19- 200845536 此外，振動型電磁發電機40係複數個磁鐵及複數個 螺線管線圈之組合之構成，然而，亦可以爲3個以上之磁 鐵、及4個以上之螺線管線圈之組合來構成振動型電磁發 電機。 此外，上述實施形態時，相鄰之螺線管線圈間具有間 隔，然而，亦可以樹脂等之構件來形成隔離件。此外，亦 可以磁性體及非磁性體之磁鐵隔離件之組合來構成可動磁 • 鐵。 此外，上述實施形態時，可動磁鐵之形狀爲圓筒型， 然而，剖面形狀亦可以多角形、橢圓形、或曲線及直線之 組合形狀。此時，螺線管線圈及磁鐵隔離件之剖面形狀， 只要爲可與可動磁鐵之剖面形狀對應之形狀即可。 此外，亦可於螺線管線圈之內徑，配設導引軌，並於 可動磁鐵之側面裝設滾子滾子。相反地，亦可於螺線管線 圈之內徑配設滾子，並於可動磁鐵配設導引軌。此種構成 φ 時，即使只施加少許力，亦可使可動磁鐵順暢滑動，而具 有得到發電力之效果。 【圖式簡單說明】 第1圖係振動型電磁發電機之1個圓筒型磁鐵通過螺 線管線圈時所發生之輸出電壓波形例之說明圖。 第2圖係振動型電磁發電機之構造例之剖面圖。 第3圖係可動磁鐵通過第1〜第3螺線管線圈時之輸 出電壓波形例之槪念圖。 -20- 200845536

OBJECT OF THE INVENTION [Technical Field] The present invention relates to, for example, vibration of a power generation voltage by vibrating or moving a plurality of cylindrical magnets magnetized in the longitudinal direction in a plurality of solenoid coils Method for manufacturing electromagnetic generator and vibration type electromagnetic generator. In particular, the present invention relates to a vibrating electromagnetic generator Φ and a manufacturing method of a vibrating electromagnetic generator in which a plurality of magnets are integrated with the same polarity and spaced apart from each other to increase power generation efficiency. [Prior Art] In recent years, the number of portable electronic devices such as mobile phones and game machines has continued to increase, and the number of batteries built into these batteries has increased. In addition, with the development of wireless technology, the application of RFlD (Radio Frequency IDentification) for transmitting and receiving signals with small power has been further expanded. In particular, active RFID with power supply can communicate over hundreds of meters. Therefore, the health management of cattle and horses used in pastures, and the safety management of students when they go to school are expected. On the other hand, in order to maintain the improvement of the global environment, the development of batteries that reduce the environmental load as much as possible is also very active. Among them, the concept of using the energy that is usually unconsciously converted into electric energy and charging it to use the electric energy as a power source for a portable device or the like is widely observed. Patent Document 1 is provided with a movable magnet in which a plurality of permanent magnets magnetized in the longitudinal direction are integrated with a small distance and opposite poles, and -5-200845536 is a coil of opposite polarity in which the polarities of adjacent plural coils are reversed. The vibration generator in the way of moving. Patent Document 2 describes a generator that is configured such that a surface of the same polarity of a plurality of magnets is joined to each other and a polarity of an adjacent coil is reversely connected. [Patent Document 1] JP-A-2006-296 1 44 [ In the inventors of the present invention, the inventors of the present invention further reviewed the conditions for the purpose of improving power generation efficiency. As a result, it has been found that the pitch of the magnet determined by the total length of the magnet (the length of the magnet) and the small distance (the thickness of the spacer) and the coil pitch determined by the total length of the turns and the total interval of the coils are matched. A plurality of magnets and a plurality of coils constitute the most important requirement for a vibrating electromagnetic generator. When φ fails to satisfy this condition, the phase of the voltage occurring in the plurality of coils deviates, and the voltages are offset each other, and the resultant output voltage is lowered. However, Patent Document 1 does not have a description that the magnet pitch and the coil pitch must be uniform, and it is not clear how to determine the length of the reference magnet. Further, a plurality of magnets 'the constituent elements of the generator shown in Patent Document 2 are directly joined to the same pole without using the magnet spacer. In addition, the coils of the plurality of coils are not provided with coil spacing. In addition, the specific determination method of the magnet size and the coil size for the purpose of improving the power generation efficiency is not disclosed. -6 - 200845536 In addition, when the same pole of the magnet is directly joined as shown in Patent Document 2, power generation occurs due to demagnetization. The efficiency is degraded. In addition, because the reaction force of the same pole is extremely large, there is a problem that the joining operation is difficult. SUMMARY OF THE INVENTION An object of the present invention is to provide a vibration type electromagnetic generator which is smaller in size and has higher power generation efficiency by providing a specific condition for the purpose of improving the power generation efficiency by clarifying the conventional vibration type electromagnetic power generator. The vibrating electromagnetic generator of the present invention is composed of: a power generating coil in which a plurality of solenoid coils are connected in series; and a plurality of power generating coils that are movable in the direction of the reel in the inner side of the power generating coil, and are opposite to each other in the same manner as the magnetic poles The movable magnet of the magnet; Next, the plurality of spiral lines have a predetermined coil spacing and are wound in opposite directions, and the movable magnets are joined by the magnet spacers of a predetermined thickness in the same polarity, and in addition, the plurality of spirals The coil pitch of the total length of the coil of the coil and the interval of the coil is substantially equal to the pitch of the magnet of the total length of the magnet of each movable magnet and the thickness of the magnet spacer, and the coil length is shorter than the length of the magnet. Further, the present invention includes: a power generating coil in which a plurality of solenoid coils are connected in series; and a movable magnet including a plurality of magnets that are movable in a reel direction inside the power generating coil and are opposite to each other in a magnetic pole And a plurality of solenoid coils having a predetermined coil spacing and wound in mutually opposite directions, and the movable magnets are joined by the magnet spacers of a predetermined thickness in a manner of opposing poles, and in addition, the plurality of spirals The coil pitch of the coil coil coil and the total coil spacing is the same as the total length of the magnet length of each movable magnet and the thickness of the magnet spacer. The magnetic spacing is approximately equal, and the coil length is shorter than the magnet. A method of manufacturing a vibration type electromagnetic generator having a length. The method for manufacturing a vibration type electromagnetic generator includes the steps of: producing a solenoid coil having a predetermined coil diameter and a predetermined number of windings per unit length, and a coil length of at least three times a coil diameter; A step of setting the starting characteristic φ of the output voltage when the magnet having the predetermined magnet diameter and the length of the coil is substantially the same length through the spiral passage at a certain passing speed; obtaining the starting characteristic from 10% of the maximum amplitude to 90 The step of starting time up to %; and the step of using the length of the distance between the start time and the passing speed to be twice the length of the magnet pitch. According to the present invention, since the optimum magnet spacer, magnet, coil, and coil interval can be designed, a vibration type electromagnetic generator capable of improving power generation efficiency can be obtained. According to the present invention, in order to increase the optimum design of the number of magnets and the number of coils, the effect of maximizing power generation can be obtained. In addition, because the optimum φ magnet spacers, magnets, coils, and coil spacing can be designed, the effect of reducing the size of the generator can be obtained. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to Figs. 1 to 12 . In the present embodiment, an example of a vibration type electromagnetic power generator that generates power by moving a magnet provided in a solenoid coil in addition to vibration from the outside will be described. First, a specific configuration example of the vibration type electromagnetic power generator of the present invention -8 - 200845536 will be described with reference to Figs. 1 to 3, and a generator including a movable magnet and a solenoid coil will be described. Fig. 1 is a view showing an example of a configuration of a vibrating electromagnetic generator 10 composed of one cylindrical magnet 2 and one solenoid coil 1, and an output voltage waveform. The length of the solenoid coil 1 constituting the vibration type electromagnetic power generator 10 is substantially equal to the length of the cylindrical magnet 2. Next, the output voltage obtained when one cylindrical magnet 2 φ passes in the direction of the reel of the solenoid coil 1 is represented by the output voltage waveform 3. The period of the output voltage waveform 3 is approximately twice the length of the magnet or the length of the coil (the length of the solenoid coil), and is approximately equal to the waveform of one cycle of the waveform of the sine wave. That is, in Fig. 1, when the horizontal axis of the output voltage waveform is used as the time axis, the period of one cycle is divided by the length of the magnet twice the distance obtained by dividing the velocity. However, the vibration type electromagnetic generator of the present invention is composed of a solenoid coil φ and a movable magnet that operates in a solenoid coil. The movable magnet is composed of a plurality of magnets that are joined to each other with the same polarity. Further, the solenoid coil is composed of a plurality of coils of reverse polarity in series. Next, the output voltage of the vibrating electromagnetic generator of the present invention is obtained by the output voltage generated by each solenoid coil by a movable magnet operating in a solenoid coil. At this time, the waveform of the output voltage generated by each solenoid coil is based on the voltage waveform shown in Fig. 1. Secondly, it is extremely important to match the phase of the voltage generated by all the coils to make this voltage the maximum output. Therefore, the magnet spacing plus the length of the magnet and the thickness of the magnet spacer, and the coil pitch plus the -9-200845536 coil length and coil spacing must be approximately equal. Further, when the materials of the magnets are the same, in order to obtain a small generator having a higher power generation efficiency, how to obtain a large output voltage with a shorter magnet length is an important issue. Therefore, the inventors of the present invention carried out verification of the characteristics of the vibration type electromagnetic power generator of the present invention under various conditions. Fig. 2 is a cross-sectional view showing a vibrating electromagnet generator 20 composed of one movable magnet 25 and three solenoid coils (first solenoid coil 2 1 to third solenoid coil 23). Adjacent spiral lines have a defined spacing 24. The winding direction of the coil is the positive, negative, and positive directions in which the adjacent solenoid coils are opposite each other. The first solenoid coil 21 to the third solenoid coil 23 connected in series are referred to as a power generating coil 26. The length of the movable magnet 25 is equal to the total length of the coil and the interval of the coil (e.g., the total length of the solenoid coil 21 and the gap 24). Fig. 3 is a view showing the waveform of the output voltage when the movable magnet 25 passes through the first solenoid coil 21 to the third solenoid coil 23 which are connected in series with the polarity of the positive, negative and positive. The horizontal axis scale of Fig. 3 corresponds to the length of the magnet (= coil length). In Fig. 3, the numbers in the table are the amplitude ratios of the output voltage of each solenoid coil and the combined output voltage. The polarities of the first solenoid coil 21 to the third solenoid coil 23 are positive, negative, and positive, respectively. Therefore, the voltage generated in each of the first solenoid coil 21 to the third solenoid coil 23 causes a phase shift corresponding to the length of the coil and changes the polarity. -10- 200845536 Further, the first solenoid coil 21 to the third solenoid coil 23 are connected in series with each other. Therefore, the obtained voltage is the combined output voltage of the voltage generated by the first solenoid coil 2 1 to the third solenoid coil 23 . At this time, the composite output voltage waveform shown in Fig. 3 is obtained. Next, a configuration example of the vibration type electromagnetic generator 40 of the present invention will be described with reference to a cross-sectional view of Fig. 4. The vibration type electromagnetic generator 40 is composed of one movable magnet 48 and three φ solenoid coils (the first solenoid coil 41 to the third solenoid coil 43). Adjacent solenoid coils are spaced apart by a predetermined interval 44. The winding direction of the coil is the positive, negative, and positive directions in which the adjacent solenoid coils are opposite each other. The first solenoid coil 41 to the third solenoid coil 43 connected in series are referred to as a power generating coil 49. The movable magnets 48 are integrally joined to each other by the same poles of two magnets 45 and 46 of the same length magnetized in the longitudinal direction via a magnet spacer φ 47 composed of a non-magnetic material having a predetermined thickness. The magnet pitch 5 1 of the total length of the magnet and the magnet spacer 47 is equal to the coil pitch 52 of the total size of the solenoid coil and the solenoid coil interval. However, even under this condition, it is preferable that the coil length is shorter than the length of the magnet. Fig. 5 is a view showing the waveform of the output voltage when the two magnets 45 and 46 pass through the first solenoid coil 41 to the third solenoid coil 43 which are connected in the positive and negative directions shown in Fig. 4 . In Fig. 5, the numbers in the table are the amplitude ratios of the output voltages of the respective solenoid coils and the combined output voltage. -11 - 200845536 When two magnets 45 and 46 of different polarities pass through the respective solenoid coils, a voltage is generated at each solenoid coil when the phase is located at the corresponding coil length. The output voltage synthesized by all of these voltages is the composite output voltage waveform shown in Fig. 5. As shown in Figs. 2 and 4, the vibrating electromagnetic generators 20 and 40 are arranged such that the magnet and the solenoid coil are arranged close to each other. Therefore, as shown in Figs. 3 and 5, there is a basic characteristic in which the output voltage is combined so that one part of the amplitude φ is several times. The inventors of the present invention wish to use this basic characteristic to increase the output power of the vibration type electromagnetic power generator. Next, in the vibration type electromagnetic generator of the present invention, it is extremely important that the magnet pitch 5 1 and the coil pitch 52 are equal. Here, the distribution of the magnetic field formed by the cylindrical magnet 60 in the space will be described with reference to Fig. 6. Fig. 6 is a cross-sectional view showing the distribution of the magnetic field formed by the cylindrical magnet 60 in the space. As can be seen from Fig. 6, the magnetic field near the end face of the magnet can reach a direction longer than the length of the φ cylindrical magnet 60. Further, the direction of the magnetic field in the vicinity of the end surface of the cylindrical magnet 60 is parallel to the longitudinal direction of the cylindrical magnet 60. Therefore, it is necessary to effectively combine the solenoid coil and the magnetic field parallel to the length of the magnet by making the length of the coil shorter than the length of the magnet. In the description so far, in order to improve the power generation efficiency, it is necessary to make the magnet pitch and the coil pitch equal, and it is necessary to make the coil length shorter than the magnet length. Hereinafter, a method of determining the optimum magnet length and the magnet pitch for the purpose of improving power generation efficiency will be described. Fig. 7 is a practical example of the output voltage characteristics obtained by passing four types of cylindrical magnets having different magnet lengths at a speed of -12 - 200845536 degrees 1 · 2 m / s through a solenoid coil of a certain coil length. The four types of cylindrical magnets have a diameter of 4 mm, however, the magnet pitches are different from 8 mm, 16 mm, 24 mm, and 32 mm. The solenoid coil has an inner diameter of 6 mm, a number of windings per unit length of 60 times, and a coil length of 30 mm. As can be seen from Fig. 7, the starting characteristic of the output voltage when the length of the magnet is increased is substantially the same as the length of any of the magnets. Secondly, the maximum value of the output voltage is also approximately constant when the length of the magnet is increased from 8 mm to 16 mm and the length of the magnet is increased from 16 mm to 32 mm. However, as the length of the magnet increases, the duration of the maximum 値 of the output voltage also becomes longer. Further, as shown in Fig. 7, the starting characteristics hardly change due to the length of the magnet. Therefore, the reason for determining the starting characteristics is the diameter of the magnet and the size of the solenoid coil, and in particular, the inner diameter of the solenoid coil. Therefore, by making the inner diameter of the solenoid coil close to the diameter of the magnet, the start-up time can be further shortened. Here, the focus is placed on a cylindrical magnet having a maximum output voltage of 16 mm, 24 mm, and 32 mm. According to the starting characteristics of the output voltage of Fig. 7, the output voltage is obtained from 10% of the maximum 90 to 90%. time. At this time, as shown in the figure, it is about 5 ms. At this time, since the moving speed of the magnet is 1.2 m/s ′, the moving distance corresponding to twice the starting time of 5 ms is 12 (m/s) x 5 (ms) x 2 = 12 mm. That is, the length of the magnet is 12 mm, so that the output voltage is approximately equal to the maximum 値', and the length of the magnet can be minimized. -13- 200845536 Fig. 8 shows an example of the output voltage characteristics when a cylindrical magnet of a certain magnet length is passed through three types of solenoid coils having different coil lengths. The cylindrical magnet has a diameter of 4 mm and a magnet length of 8 mm. The number of coils per unit length of the solenoid coil is equal, and the coil length is different from 7 mm, 10 mm, and 30 mm. As can be seen from Fig. 8, when the length of the magnet is 8 mm, the coil length is increased from 7 mm to 10 mm, and the output voltage is only increased a little. In addition, even if the coil length is increased from 7 mm to 30 mm, the maximum amplitude of the output voltage is almost constant (about 0.5 V). That is, with respect to a magnet having a length of 8 mm, as shown in Fig. 1, the coil length is 8 mm which is the same length as the length of the magnet, and the output voltage is substantially the maximum 値 (saturation voltage). An example of a vibration type generator in which a movable magnet is used will be described with reference to Figs. 7 and 8. However, when a vibrating generator 40 composed of a plurality of magnets (at least two or more) and a plurality of solenoid coils is used, the output voltage can be selected for a predetermined coil size under the same conditions. For the shortest possible magnet spacing. In other words, the distance between the magnets of the total length of the magnet and the thickness of the spacer, and the coil pitch of the total length of the coil and the coil interval are equal, and high power generation efficiency can be obtained, and the overall size can be reduced. Further, it is preferable that the magnet pitch and the coil pitch are made equal and the coil length is shorter than the magnet length. In this way, when the vibration type -14-200845536 dynamic electromagnetic generator 40 is composed of a plurality of magnets and a plurality of solenoid coils, the length of the magnet having the shortest output voltage can be selected for the predetermined solenoid coil size. Therefore, the vibration type electromagnetic generator 40 having high power generation efficiency can be obtained even if the size is small. Hereinafter, a description will be given of a procedure for obtaining an optimum magnet pitch for the purpose of improving power generation efficiency. (1) First, a spiral line coil having a predetermined coil diameter and a predetermined unit length is prepared, and the coil length is at least three times the coil diameter. (2) Next, a magnet having a predetermined magnet diameter and a coil length of substantially the same length is passed through the solenoid coil at a constant speed, and the starting characteristic of the output voltage at this time is measured. (3) The time from the maximum amplitude of 10% to 90% when the starting characteristic is obtained. (4) As a result, the length of the distance is approximately twice as large as the time taken and the passing speed, and the pitch of the magnet is obtained. After obtaining the magnet spacing, the coil length and the coil spacing are set to be equal to the magnet spacing, and the magnet length is longer than the coil length of the solenoid coil, and the coil spacing and the magnet are set. The dimensional condition of the spacer. In this way, a vibration type electromagnetic generator which is close to the maximum output voltage and which can reduce the size of the generator body can be obtained. Further, as described above, the predetermined coil diameter, the number of windings of each unit length, and the predetermined magnet diameter represent the dimensions of the vibrating electromagnetic generator used. Here, an example of the external configuration of the vibration type electromagnetic generator -15-200845536 40 will be described with reference to a perspective view of Fig. 9. Fig. 9A is a perspective view showing a state in which the respective members of the vibration type electromagnetic power generator 40 are constructed. Fig. 9B is a partial perspective view of the housing case 55 of the vibration type electromagnetic generator 40 in which the respective members are combined. The first solenoid coil 41 to the third solenoid coil 43 are wound around the outer circumferential surface of the cylindrical housing case 55 in which the movable magnet 48 is housed via the solenoid coil interval 44. The first solenoid coil 4 1 to the third solenoid coil 43 are connected in series. Next, each of the solenoid coils is wound in opposite directions to each other, which are a positive winding, a reverse winding, and a positive winding. The coil end portion 53 is extended from each of the first solenoid coil 41 and the third solenoid coil 43, and is connected to an external member (load) (not shown). In order to accommodate the movable magnet 48 in the storage case 55, end caps 56 are attached to both ends of the storage case 55. The end cap 56 is formed of a resin or the like which can alleviate the impact on the movable magnet. In order to allow the movable magnet 48 to smoothly move inside the housing case 55, the movable magnet 48 can be moved in the direction of the reel inside the first solenoid coil 41 to the third solenoid coil 43. Therefore, the first solenoid coil 41 to the third solenoid coil 43 can generate a voltage and have a function as a generator. Here, an actual measurement example of the output voltage waveform obtained by actually using the vibration type electromagnetic power generator 40 will be described with reference to Fig. 1 . In the movable magnet, two Nd (钹) magnets having a diameter of 4 mm and a length of 8 mm were formed by the same poles being joined to each other via a magnet spacer having a thickness of 1.5 mm. -16- 200845536 The solenoid line system is constructed by connecting three coils with a length of 6.5 mm, a coil inner diameter of 5 mm, and a number of turns of 3000 turns in a series of positive, negative, and positive coils with a coil spacing of 3 mm. Next, Fig. 10 is an output voltage waveform when the movable magnet is moved at a speed of about 1.2 m/s along the winding bobbin in the solenoid coil. Comparing the composite output voltage waveforms of Figures 10 and 5, the two are fairly consistent. It represents the appropriateness of the φ content explained with reference to Figs. 1 to 5 . Here, an example of the magnetic flux density of each of the movable magnets having different materials of the magnet spacer will be described with reference to Figs. 1 and 12 . Fig. 1 is a view showing a configuration example of a cylindrical magnet and a movable magnet that joins a cylinder and a magnet via a magnet spacer. Fig. 1 is a configuration example of a cylindrical magnet 61. The cylindrical magnet 6 1 has a length of about 1 mm in the axial direction and a diameter of about 5 mm. Fig. 1B is a configuration example of the magnet spacers 7 1 and 81. The material forming the magnet φ spacer 71 is made of, for example, a resin as a non-magnetic material. The material forming the magnet spacer 81 is made of, for example, pure iron as a magnetic material. The magnet spacers 71, 81 have a length of about 2 mm in the axial direction and a diameter of about 5 mm. Fig. 11C is a configuration example of the movable magnets 70 and 80. The movable magnet 70 is connected to the three cylindrical magnets 6 1 in the same polarity by a magnet spacer 7 formed of a non-magnetic material. On the other hand, the movable magnet 80 is joined to the three cylindrical magnets 6 1 in the same polarity by the magnet spacers 8 1 formed of a magnetic material. -17- 200845536 Fig. 12 shows an example of measurement results of magnetic flux densities which are generated by the cylindrical magnet 61 and the movable magnets 70 and 80 in the longitudinal direction of the cylindrical magnet 61 and the movable magnets 70 and 80. Fig. 1 is a graph showing the measurement results of the magnetic flux density of one cylindrical magnet 61. Fig. 1B is a measurement result of the magnetic flux density of the movable magnet 70. Fig. 1C is a measurement result of the magnetic flux density of the movable magnet 80. In Fig. 12A to Fig. 12C, the vertical axis representing the magnetic flux density is provided with equally spaced scales (B: ~ B6) for comparison of the figures. As shown in Fig. 12A, in general, the end portion of the cylindrical magnet 61 (near the N pole and the S pole) has a high magnetic flux density due to the concentration of the magnetic flux. Further, as shown in Fig. 12 and Fig. 12 As shown in Fig. C, the vicinity of the N pole and the S pole of the movable magnet that is joined to the same pole has a peak value higher than the magnetic flux density of one cylindrical magnet 61. This is because the magnetic poles are repulsive and the magnetic flux density is increased because the same poles are relatively joined. Further, as compared with the case of FIG. 12B and FIG. 12C, it is understood that the peak of the magnetic flux density of the movable magnet 80 including the magnet spacer 81 formed of the magnetic material is higher than that of the non-magnetic material. The movable magnet 70 of the magnet spacer 7 1 . At this time, the peak of the movable magnet 80 is 3/2 times higher than the peak of the movable magnet 70. The magnet spacer 81 formed of the magnetic material having high magnetic permeability easily pulls the magnetic force line from the cylindrical magnet 61, and has high magnetic beam directivity and a higher magnetic flux density. According to the measurement results of FIG. 12A to FIG. 12C, when the vibration type generator is constituted by the movable magnet 80 including the magnet spacer 81 formed of the magnetic material of the magnetic-18-200845536, the magnetic flux density is high and the snail is The wire tube coils have more magnetic fluxes. Therefore, when the material used for the magnet spacer is a magnetic material, the vibration type electromagnetic generator has higher power generation efficiency than the non-magnetic material, as shown in the above description, and is clearly defined to improve vibration. The specific efficiency of the power generation efficiency of the electromagnetic generator 40 can be appropriately designed. The magnet pitch and the coil pitch of the 0-vibration electromagnetic generator 40 are appropriately designed. Therefore, there is an effect that a vibration type electromagnetic generator 40 which is small in size and high in power generation efficiency can be obtained. Further, the configuration of the vibration type electromagnetic generator 40 is simple. Therefore, the process at the time of assembly is relatively easy, and the vibration type electromagnetic generator 40 which is less susceptible to damage and high reliability can be obtained. Further, when the magnet spacer is a magnetic body, since the magnetic flux density can be increased, the power generation of the vibration type electromagnetic generator can be improved. Therefore, when φ is focused on the amount of power generation, even if the external size is smaller than the vibration type electromagnetic generator using the magnet spacer formed of the non-magnetic material, the same power generation amount can be obtained. At this time, the number of windings of the solenoid coil can also be reduced. Therefore, the vibration type electromagnetic generator can be more compact and lighter. In addition, by reducing the amount of components used, there is an effect of reducing costs. On the other hand, the magnet spacer is a non-magnetic material, and has a smaller manufacturing effect than when the magnet spacer is a magnetic body. Further, since a non-magnetic material can be made of a synthetic resin such as plastic, it has an excellent workability and a high manufacturing speed. -19- 200845536 The vibrating electromagnetic generator 40 is a combination of a plurality of magnets and a plurality of solenoid coils. However, it may be a combination of three or more magnets and four or more solenoid coils. To form a vibrating electromagnetic generator. Further, in the above embodiment, the gap between the adjacent solenoid coils is spaced apart, but the spacer may be formed by a member such as a resin. Further, a movable magnetic iron may be formed by a combination of a magnetic body and a non-magnetic magnet spacer. Further, in the above embodiment, the shape of the movable magnet is a cylindrical shape. However, the cross-sectional shape may be a polygonal shape, an elliptical shape, or a combination of a curved line and a straight line. In this case, the cross-sectional shape of the solenoid coil and the magnet spacer may be any shape that corresponds to the cross-sectional shape of the movable magnet. In addition, a guide rail may be disposed on the inner diameter of the solenoid coil, and a roller roller may be disposed on the side of the movable magnet. Conversely, a roller can be disposed on the inner diameter of the solenoid line ring, and a guide rail can be disposed on the movable magnet. In the case of such a configuration φ, even if only a small amount of force is applied, the movable magnet can be smoothly slid and the power can be generated.
